Answer:
The volume of reactant measured at STP left over is 409.9 L
Explanation:
Answer:
Mass, m = 19466.7 kg
Explanation:
Given that,
Portland cement concrete (PCC) has a density of 150 lb/ft³
We need to find how many kilograms of PCC are required to cast a cylindrical column 1.15 m in diameter and 7.8 m in height.
Since, 1 kg = 2.205 lb
1 lb/ft³ = 16.018 kg/m³
150 lb/ft³ = 2402.77 kg/m³
Density, 
m is mass of PCC in kg and V is volume of cylinder


So, the mass of PCC required is 19466.7 kg.
