The answer is 14.22 mg / (mm^2)
The grams of NaCl that are required to make 150.0 ml of a 5.000 M solution is 43.875 g
calculation
Step 1:calculate the number of moles
moles = molarity x volume in L
volume = 150 ml / 1000 = 0.15 L
= 0.15 L x 5.000 M = 0.75 moles
Step 2: calculate mass
mass = moles x molar mass
molar mass of NaCl = 23 + 35.5 = 58.5 mol /L
mass is therefore =0.75 moles x 58.5 mol /l =43.875 g
Answer:
29,200 cal = 1.22 E 5 joules
Explanation:
hope this helps
Empirical formula is the simplest way the molecular formula can be wrote so here 7 goes into all of these so it would be CH2O
