What is the percent by mass of CaCl2, when 35 grams are dissolved in enough water to produce 3 kg of solution?
A) 12%
B) 8.6%
C) 86%
D) 1.2%

A) 1.2%

Explanation:

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
