Answer: 0.067 litres of water
Step-by-step explanation:
The mode is:
Concentration of new solution = Moles of acid in original solution / (Volume of original solution + Volume of water added)
Assume volume of water added is w.
12 = 16 (0.2) / (0.2 + w)
(0.2 + w) * 12 = 3.2
0.2 + w = 3.2 / 12
w = (3.2 / 12) - 0.2
w = 0.067 litres of water
Answer:
Volume = = 138⁶/32 cubic meters
Step-by-step explanation:
Given:
Length = 8⅜ m
Width = 2 m
Height = 8¼ m
Required:
Volume as a mixed number
Solution:
Volume of rectangular prism = L*W*H
Plug in the values
V = 8⅜ × 2 × 8¼
Change to improper fraction
V = 67/8 × 2 × 33/4
= (67 × 2 × 33)/(8 × 4)
= 4,422/32
= 138⁶/32 m³
Answer:
Step-by-step explanation:
take 45 degree as reference angle
using sin rule
sin 45 =opposite /hypotenuse
1/
=24/k(do cross multiplication)
24=k
The third one because it matches plus im copy
I believe -23 and -24 because it is below sea level.
