Answer:

the sum is Rs 4,200

Explanation:

Given that

3 by 7 of the sum is $1,800

We need to find out the sum

So,

Here we assume the sum be x

So the following equation should be made

3 ÷ 7 × x = 1800

3x = 1800 × 7

x = (1800 × 7) ÷ 3

= Rs 4,200

Hence, the sum is Rs 4,200

The same would be considered and relevant

What volume of concentrated (10.2 M) HCl would be required to prepare 1.11 x 104 mL of 1.5 M HC1? Enter your answer in scientifi

Tomtit [17]

Answer:

The required volume is 1.6 x 10³mL.

Explanation:

When we want to prepare a dilute solution from a concentrated one, we can use the dilution rule to find out the required volume to dilute. This rule states:

C₁ . V₁ = C₂ . V₂

where,

C₁ and V₁ are the concentration and volume of the concentrated solution

C₂ and V₂ are the concentration and volume of the dilute solution

In this case, we want to find out V₁:

C₁ . V₁ = C₂ . V₂

$V_{1} = \frac{C_{2}.V_{2}}{C_{1}} = \frac{1.5M \times1.11.10^{4}mL }{10.2M} =1.6\times10^{3} mL$
