The answer is b to be sure
White sheep: 162 black sheep: 18
Numbers are a ratio of 9: 1, total 10 parts
180/10 =18
18 x 9 =162 18 x 1 =18
KCl has a molecular weight of 39+35 = 74 grams per mole, so 2 moles will have a mass of 148 grams.
Assuming the water has a density of 1000 grams per liter, the mass percentage of the KCl solution is 148/(1000+148) ≈ 0.12892 ≈ 12.9%
Answer:
I would shade 50 squares
Step-by-step explanation:
"Of" is the same as multiplication so,2/4×100/1=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
2×100/4×1=200/4
Since 200 divided by 4 equals 50 then, 200/4=50
Therefore: 2/4 of 100/1=50
