How many moles are there in 276 grams of ethanol CH3 CH2 OH

6 moles

Explanation:

We'll begin by obtaining the molar mass of ethanol (CH3CH2OH). This is illustrated below:

Molar Mass of CH3CH2OH =

12+(3x1)+12+(2x1)+16+1

= 12+3+12+2+16+1

= 46g/mol

Mass of CH3CH2OH from the question = 276g

Number of mole CH3CH2OH =?

Number of mole = Mass /Molar Mass

Number of mole CH3CH2OH = 276/46

Number of mole CH3CH2OH = 6 moles

Therefore, there are 6 moles in 276g of ethanol(CH3CH2OH)

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
