PLEASE HELP TIMED The host is calculating how many grams of limestone will be washed away by 30 kg of sulfur. He first converted kilograms to grams. Then he multiplied by which of these?
A.
The reciprocal of the molar mass of sulfur
B.
The molar mass of sulfuric acid
C.
The reciprocal of the molar mass of limestone

The reciprocal of the molar mass of sulfur

Explanation:

The number of grams = n

Mass of Sulphur, m = 30 kg

Molar mass of Sulphur, M = 32.1 g

The formula used :

n = m / M

Converting m in kg to gram

1000g = 1kg

(1000/kg) ÷ 32

To change the ÷ sign to *, we multiply by the reciprocal of the divisor

The divisor is the molar. Mass of Sulphur

Hence, we have ;

30*(1000g/kg) * (1/32.1)

format change of dna.
