Astudent produces 1.34g of mgnh4po4*6h2o (mm =245.1 g/mol) from a sample of fertilizer, how grams of phosphorous were in the fertilizer?

of phosphorus is present in 1.34 g of fertilizer.

Further Explanation:

Mole is a measure of the amount of substance. It is defined as the mass of a substance that has the same number of fundamental units as there are atoms in 12 g of carbon-12. Such fundamental units can be atoms, molecules or formula units.

The formula to calculate the moles of fertilizer is as follows:

                …… (1)

The given mass of is 1.34 g.

The molar mass of is 245.1 g/mol.

Substitute these values in equation (1)

The chemical formula of the fertilizer is . This indicates that one mole of the fertilizer contains one mole of phosphorus.

So the number of moles of phosphorus in 0.0054671563 moles of fertilizer can be calculated as follows:

The formula to calculate the mass of phosphorus is as follows:

…… (2)

The number of moles of phosphorus is 0.0054671563 mol.

The molar mass of phosphorus is 30.97 g/mol.

Substitute these values in equation (2).

So, 0.17 grams of phosphorus is present in the fertilizer.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

gas

explanation:

smoke is the matter of a gas
