Answer:
a. 30 cm³
b. 4.33 g/cm³
Explanation:
a Volume of the object = l*w*h
l = 5 cm
w = 2 cm
h = 3 cm
Volume of object = 5*2*3 = 30 cm³
b. Density of the object = mass of the object / its volume
Mass of object = 130 grams
Volume = 30 cm³
Density of the object = 
Answer:
Updrafts continue to fuel the storm with warm, moist air. But, once a storm runs out of updrafts, it starts to weaken. As a storm begins to slow down, the rain and wind become less intense. And by the end, all that's left is a blue sky and an anvil-shaped cloud top.

Answer:
The solution is 0, 90 molal. See the explanation below, please
Explanation:
Molality is defined as moles of solute in 1 kg of solvent (1000 grams). The following three simple rule must be performed:
We calculate the weight of 1 mol of CaCl2
Weight Ca =40, 078 g
Weight Cl= 35, 453 g
Weight of 1 mol of CaCl2=40, 078g + 2x (35, 453g )= 110, 98g
110, 98 g ---1 mol
25 g---X= (25g x1 mol)/110, 98g= 0,23mol
250g solvent -----0,23 mol CaCl2 (the solute)
1000g solvent ----X = (1000g x0,23mol)/250g =0,90 mol solute
The solution is 0,90 molal
