What is the volume , in cubic meters, of a rectangular solid that is 0.25 m long and 6.1 m wide and 4.9 m high
1 answer:
To find the volume, we must first make sure that each of the dimensions is in the correct units before we make the calculation. Since we want cubic meters, and every dimension is in meters, we are good to go in this case.
So to solve for the volume, we must multiply each of the sides together:
If the answer must be in significant figures, then we know that we must only use two significant figures in this case, and so the volume would then be .

Explanation:
25. Boyle's Law
The temperature and amount of gas are constant, so we can use Boyle’s Law.

Calculations:
26. Ideal Gas Law
We have p, V and n, so we can use the Ideal Gas Law to calculate the volume.
pV = nRT
Data:
p = 101.3 kPa
V = 20 L
n = 5 mol
R = 8.314 kPa·L·K⁻¹mol⁻¹
Calculation:
101.3 × 20 = 5 × 8.314 × T
2026 = 41.57T
