If 24.6 grams of chromium, 11.8 grams of oxygen, and 1.2 grams of hydrogen combine to form a compound. What is the percent composition by mass of chromium

Answer 1

Explanation:

a man out of chronium 8 = 24.6 grams

mass of oxygen = 11.8 grams

mass of oxygen = 1.2 grams

total mass =24.6 + 11.8 + 1.2

=37.6

percent composition by mass of chromium

= 24.6/37.6 = 0.654
