Molar mass of aspirin =180. So, moles of aspirin = 500 × 1 0 − 3 / 180 = 2.78 × 1 0 − 3 = 278 × 1 0 −
Answer:
5.4 tonnes.
Explanation:
The first step is to find the molar mass of Al2O3. Aluminum has a molar mass of about 27 and oxygen has a molar mass of about 16, so 2(27)+3(16)= 102g/mol=0.102kg/mol. 10200kg/0.102kg/mol=100,000 moles of Al2O3 in 10.2 tonnes. Multiplying this by the molar mass of the two aluminums, you get a total of 54*100,000=5400000g=5400kg=5.4 tonnes. Hope this helps!

Answer:
75 g
Step-by-step explanation:
<em>Step 1</em>. Calculate the molar mass of CO₂
C = 12.01
2O = 2 × 16.00 = <u>32.00
</u>
Total = 44.01 g/mol
<em>Step 2</em>. Calculate the mass of CO₂
Mass of CO₂ = 6 mol CO₂ × (44.01 g CO₂/1 mol CO₂)
Mass of CO₂ = 75 g CO₂
