<h2>Answer:</h2>
Given data:
Volume of solution: 500 ml
Mass of 10 ml solution: 10.7 g
Density of whole solution: ?
<h3>Solution:</h3>
Mass of 500 ml solution : 10.7/10 * 500 = 535 g
Density = Mass/ volume
<u>Putting values in formula :</u>
D = 535/500 = 1.07 g/ml
Hence Density = 1.07 g/ml
Answer:
a.is the same as science
c. influences science
e. helps scientists observe fast phenomena
Explanation:
Hey there!
Given the reaction:
4 AI + 3O2 ------> 2 AI2O3
4 moles Al --------- 3 moles O2
9.30 moles Al --------- ?? moles O2
9.30 * 3 / 4 => 6.975 moles of O2
Molar mass O2 => 32.0 g
Therefore:
6.975 * 32.0 => 223.3 g of Oxygen
Hope that helps!
