For moles to grams would be the mole which is 7.9*10^-1 times the molar mass of argon
Answer:
One serving is 1/4 cup therefore 1 cup would be 4 servings. Since we have 9 cups we would then multiply 9 x 4 and the answer would be 36 servings. You have a ratio of cups to serving, so 1/4 cup : 1 serving, or .
Explanation:
The empirical formula CH₂ has a mass [(12 × 1) + (1 × 2)] = 14 g/mol
If the empirical formula is 14 g/mol,
and the molecular formula is ~140 g/mol
Then the multiple is = 140 g/mol ÷ 14 g/mol
= 10
Therefor the molecular formula is 10(CH₂) = <span>C</span>₁₀<span>H</span>₂₀<span> </span>
Explanation:
<u>Photovoltaic means electricity from light</u>
photo = <em>light </em> voltaic = <em>electricity</em><em> </em>
<u>SUNLIGHT</u> is the answer
Hope this is correct
HAVE A GOOD DAY!
