Chemistry
1 answer:
Yuliya22 [10]4 years ago
4 0

Answer:

The last digit is estimated

Explanation:

the last digit of any measurement is estimated, and it is this estimated digit that reflects uncertainty. The more decimal places there are the less uncertainty there is.

The number of significant figures is uncertain in a number that ends with a zero to the left of the decimal point location. The zeros in the measurement 1,300 grams could be significant or they could simply indicate where the decimal point is located.

You wish to prepare 100 mL of 0.600 M HCl from concentrated HCl (12.85 M). You are provided with a 100 mL volumetric flask and a
Soloha48 [4]

Answer:

Because we need to dispense 4.7 mL, the volume reading in the pipet is the 5.3 mL line.

Explanation:

First we use C₁V₁=C₂V₂ in order to <u>calculate the required volume of concentrated HCl</u> (V₁):

12.85 M * V₁ = 0.600 M * 100 mL

V₁ = 4.7 mL

<u>So we need to dispense 4.7 mL of the concentrated HCl solution</u>. The mark in the pipet that would contain that volume would be 10.0 - 4.7 = 5.3 mL
