equivalent weight of p2o5

Equivalent Mass = Mass of the Metal × 8 Mass of Oxygen in the Oxide. Equivalent Mass = Mass of Oxygen in the Oxide Mass of the Metal × 8 . Equivalent weight (also known as gram equivalent) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. The ratio of a fertilizer is the relationship between the N - P2O5 - and K2O content of a fertilizer. Calculate the equivalent mass of P2O5 initially in the sample. O by weight. \text{Equivalent Mass}=\dfrac{\text{Mass of the Metal}\times 8}{\text{Mass of Oxygen in the Oxide}}. A given weight of two fertilizers can contain different amounts of actual plant food. That is, while element masses differ, when it comes to bonding with other atoms, the number of atoms, expressed in moles, is the determining factor in how much of a given element or compound will react with a given mass of another. Fertilizer ratio is the ratio of weight percents of N-P 2 O 5-K 2 O and is determined by dividing the three numbers by the smallest of the three. This might seem silly given that as you pointed out anything from $0-70\% \ \ce{P2O5}$ could just be expressed as a percentage of $\ce{H3PO4}$ but there are times when a higher $\ce{P2O5}$ concentration is desired. ... Human equivalent dose conversion by BW3/4 for RfD derivation.....76 Table 5-3. The percent loss in weight after heating a pure sample of potassium chlorate (mol. O. = 122.5) will be (K C I O 3 → K C I + O 2 ) View solution Number of g of oxygen in 3 … Again, using 10-20-10 as an example, the ratio is 10/10-20/10-10/10 = 1-2-1. 5) (CAS No. Fertilizer grades of 45-15-30, 36-12-24, and 9 … A fertilizer with a 3- 1-2 ratio contains one and a half times as much N as K2O and three times more N than P2O5. the relationship between the N - P2O5 - and K2O content of a fertilizer. The mass of a metal in its oxide is 75 % 75\% 7 5 % of the mass of the whole compound. The ratio of the fertilizer in the example above is 3-1-2. From your mass of MgNH4PO4.6H2O collected, calculate your value a) for the mass of "P2O5" in the initial mass of fertilizer analyzed b) the % "P2O5" in the fertilizer. $\ce{P2O5}$ content is useful as it is the phosphorous content that a scientist often cares about when using phosphoric acids. Suppose you analyze a sample of fertilizer by the procedure of this experiment and obtain 1.000 g of MgNH4PO4 x 6H20(s) as the product. Just want to know how i would go about this question, where would I start. The ratio of the fertilizer in the example above is 3-1-2. Could someone please help me with this? VANADIUM PENTOXIDE (V. 2. Compare this with the manufacturer's specification. One gram of hydrogen is found to combine with 8 0 g of bromine one gram of calcium valency = 2 combines with 4 g of bromine the equivalent weight of calcium is View solution Calculate the weight of C a O that can be obtained by heating 2 0 0 k g of limestone which is 9 5 % pure. I don't understand where the P205 came from. The concept of equivalent weight allows you to explore the fact that atoms combine to form molecules in fixed number ratios, not mass ratios. A fertilizer with a 3-1-2 ratio contains one and a half times as much N as K2O and three times more N than P2O5. Body weight gain and lung weights in rats (F344/N) exposed to vanadium pentoxide by inhalation for 3 months (values are means ± standard . Fertilizer grades of 45-15-30, 36-12-24, and 9-3-6 also have a 3-1-2 ratio. wt.
