We let the amount of 32% acid solution added to be X ,
Firstly, 40 of 0.12 conc. , = 4.8L of acid, and 35.2L non acid
For ever 1 L of 32% acid we add in we get 0.32L of acid and + 0.68L non Acid,
So we formulate an equation
(4.8+0.32X) / (40+X) = 16/100
(4.8+0.32X) = 0.16(40+X) =6.4+0.16X
0.16X = 1.6
X =10
Hence she used 10L of 32% Solution acid.
So you would do 41.7g - 20.2g and get 21.5g, then multiply it by 140g. 140g x 21.5g = 3010g
Answer: C. 2.889 .
Step-by-step explanation:
To find : A decimal expression equivalent to
.
When we divide 26 by 9 , we get 2.88888888889 which is approximately equal to 2.889 [Round off to the nearest thousandth place]
Hence, the decimal is equivalent to
is 2.889.
Hence, the correct option is C. 2.889 .
