Question

Please help! I have a picture of what the problem is but am not sure how to solve what it’s asking

Answer 1

62.21 gm

Step-by-step explanation:

From periodic table K = 39 I = 126.9

mole weight = 39 + 126.9 = 165.9

.750 Molar = .75 * 165.9 = 124.425 gm per LITER

you only need 1/2 of a liter so ===> 1/2 * 124.425 = 62.21 gm
