Question

find the mass of 0.25 moles of carbondioxide​

Answer 1

Answer:Gmm of Co2=(14+32)=46.

Now,

1 mole of carbon dioxide weighs =46

0.25 moles weighs =46/1*0.25 =46/4

=11.5 g.

Answer 11.5g.

Explanation:

Answer 2

Given:

• The number of moles of carbon dioxide = 0.25 moles

To Find:

• The mass of carbon dioxide.

Solution:

We have a formula saying,

Mass = molecular mass×moles → {equation 1}

{The value of molecular mass of carbon dioxide is constant, 44}

On substituting the values in equation 1 we get,

Mass = 44×0.25 {multipyling the terms}

Mass = 11g

∴ The mass of carbon dioxide = 44
