Answer:
2) 0.109 mol
Explanation:
The density of butan-1-ol is 0.8098g/mL. And its molar mass is: 74.121g/mol.
First, we need to convert volume of butan-1-ol to mass:
10.0mL * (0.8098g / mL) = 8.098g of butan-1-ol
Now, we need to convert these grams to moles using molar mass:
8.098g * (1mol / 74.121g) = 0.109 moles of butan-1-ol
Right answer is:
<h3>2) 0.109 mol
</h3>
Answer:
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight. ... Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.
