HELP ASAP!

what is the molar mass of Na2CO3?

Answer 1

The correct answer is 106.0 g/mol

Answer 2

`M_(Na_2CO_3)=106.0g/mol`

Step-by-step explanation:

Hello,

In this case, we should remember that molar mass is obtained via adding the product between the atomic mass and the subscript regarding with each element forming the compound. Thus, for sodium carbonate we have:

`M_(Na_2CO_3)=m_(Na)*2+m_C*1+m_O*3\\M_(Na_2CO_3)=23g/mol*2+12g/mol*1+16g/mol*3\\M_(Na_2CO_3)=106.0g/mol`

Best regards.
