Question

question 9 (1 point) 4 moles of co2 has mass of. 176 g 112 g 44 g 12 g

Explanation:

Step1: Recall molar - mass formula

The molar mass of $CO_2$ is calculated as follows: The molar mass of carbon ($C$) is approximately $12\ g/mol$, and the molar mass of oxygen ($O$) is approximately $16\ g/mol$. For $CO_2$, the molar mass $M = 12+2\times16=44\ g/mol$.

Step2: Use the mass - mole relationship

The mass ($m$) of a substance is related to the number of moles ($n$) and molar mass ($M$) by the formula $m = n\times M$. Given $n = 4\ mol$ and $M = 44\ g/mol$, then $m=4\times44 = 176\ g$.

Answer:

176 g
