Limestone has a density of 2.72 g/cm3. What is the mass of 8.92 cm3 of limestone?
timurjin [86]
It should be 24.2624 because if there’s 2.72g in every cm3 and there are 8.92 cm3, then you simply multiply the two numbers
hope this helped :)

eduard

Explanation:

It is assumed that the particles of an ideal gas have no such attractive forces. The motion of each particle is completely independent of the motion of all other particles. The average kinetic energy of gas particles is dependent upon the temperature of the gas.

What is the empirical formula for a substance if a 201.6 g sample of it contains 54.0 grams of nitrogen, 15.0 grams of hydrogen,
jeyben [28]

The empirical formula of the substance would be  NH_4Cl

<h3>Empirical formula calculation</h3>

The constituents of the compound are as follows:

N = 54/201.6 = 26.78% = 26.78/14 = 1.91 moles

H = 15/201.6 = 7.44% = 7.44/1 = 7.44 moles

Cl = 132.6/201.6 = 65.48% = 65.48/35.5 = 1.84 moles

Divide the number of moles by the smallest"

N = 1.91/1.84 = 1

H = 7.44/1.84 = 4

Cl = 1.84/1.84 = 1

Thus, the empirical formula is NH_4Cl
