Answer:
24 g
Step-by-step explanation:
We first find the mass of 24 % alcohol in 400 g of hand sanitizer. Let x be the mass of alcohol. So, x/400 × 100 % = 24 %
x/400 = 0.24
x = 0.24 × 400
= 96 g
The mass of the other chemicals is thus 400 g - 96 g = 304 g
We now find the mass of 30 % alcohol in 400 g of hand sanitizer. Let y be the mass of alcohol. So, y/400 × 100 % = 30 %
y/400 = 0.30
y = 0.30 × 400
= 120 g
The mass of the other chemicals is thus 400 g - 120 g = 280 g
The mass of other chemicals that needs to be evaporated is thus 304 g - 280 g = 24 g
Divide -276 by -23 to get 12. If you times -23 by 12 it’ll equal to -276
Answer:
1 1/4 in of material is cut off each board.
Step-by-step explanation:
To answer this, subtract 7 ft 10 3/4 inches from 8 ft.
First, rewrite 8 ft as 7 ft 12 inches.
Then subtract:
7 ft 12 in
- 7 ft 10 3/4 in
----------------------
1 1/4 in
1 1/4 in of material is cut off each board.
