Question

a scientist was curious about the compound found in the athletes urine. He wanted to know how many molecules of the steroid was in 75 grams of the compound. hint the molar mass of the compound is 312g/mol​

Answer 1

2.5055 x 10^24

Step-by-step explanation:

312 grams = 6.023 x 10^23 particles

75. grams= m particles

CROSS MULTIPLY

312m=75 x 6.023 x 10^23

m=(312/75) x 6.023 x 10^23

m=25.055 x 10^23

m=2.5055 x 10^24
