Question

Calculate the mass present in 5 mole of carbon dixide?



gi've me brainlaist answer,.,.,​

Answer 1

Answer:

First, we calculate the relative molecular (or atomic mass if it's an element) mass of the

substance:

CO2     M        m = 1 · 12,0 + 2 · 16,0 = 44,0 u

And then, we calculate the mass of 5 mole2 of CO2

m = 5,0 mol CO2 · 44,0 g CO2 / 1 mol CO2 = 220,0 g CO2
