Question

calculate the mass of air in a room if the floor dimensions are 10m × 12m and height is 400 cm the density of air is 1 .26 kg/M³ 3​

Answer 1

Step-by-step explanation:

first find the volume of room --->

`v \: = 10 * 12 * (400 * {10}^( - 2) ) * = 480 \: {m}^(3)`

then find the mass

`mass \: = \: density \: * \: volume \: = 480 * 1.26 = 604.8 \: kg`
