Question

4 moles of phosphorus molecule p4 find the in grams​

Answer 1

Answer:

Since the substance is the molecule P4, the molar mass of P needs to be multiplied by 4 to determine the molar mass of the molecule. n=m/M; Since M is a fraction, you can divide by multiplying by its reciprocal, 1 mol P4/123.896 g. This will cancel grams and leave moles. There is 0.801 mol P4 in 99.2 g P4.

Explanation:

Answer 2

Explanation:

Molar mass of phosphorus = 4 x Molar mass of P = 4 x 31 = 124 g.....
