Perform the following operation
xxMikexx [17]

Explanation:

3.4000x 10-6 +5.7000x 10-3

3.4000 \times  {10}^{ - 6}  = 3.4 \times  {10}^{ - 6}

5.7000 \times  {10}^{ - 3}  = 5700 \times  {10}^{ - 6}

now we can add them

3.4 + 5700 = 5703.4  \\  = 5703.4 \times  {10}^{ - 6}

= 5.7034 \times  {10}^{ - 3}

A 24% acid solution is mixed with a 14% acid solution to form a 19% acid solution. How many liters of the 24% acid solution are
Kay [80]

Answer: 5 Liters

Explanation:

According to the dilution law,

M_1V_1+M_2V_2=M_3V_3

where,

M_1 = concentration of first solution = 24%

V_1 = volume of first solution = x L

M_2 = concentration of second solution = 14%

V_2 = volume of second solution = (10-x) L

M_3 = concentration of final solution = 19%

V_2 = volume of final solution = 10 L

Putting i the values, we get:

24\times x+14\times (10-x)=19\times 10

x=5L

Therefore, 5 Liters of the 24% acid solution are used to make 10 liters of the 19% acid solution.
