2.00 kg sample of bituminous coal is composed of 1.30 kg of carbon,
0.20 kg of ash, 0.15 kg of water and 0.35 kg of volatile material.
Using this information, determine how many kilograms of carbon are in 125 kg of coal.
:
Use a ratio equation(Let C = amt of carbon in 125 kg):
2%2F125 = 1.3%2FC
2C = 125 * 1.3
2C = 162.5
C = 162.5%2F2
C = 81.25 kg of carbon in 125 kg of coal

:
Check using percent
1.3/2 = .65
81.25/125 = .65
