Answer:

0.0365

Explanation:

Given number,

0.036549,

In the above number there are 5 significant figures (i.e. 3, 6, 5, 4 and 9)

When we round a decimal number to 3 significant figure we check the fourth significant number after decimal,

if it is 5 or more than 5 then the number is rounded next significant figure it rounded to previous significant figure,

Here, the fourth significant number after decimal = 4

Thus, 0.036549 ≈ 0.0365 ( rounded to 3 significant figure )

How many milliliters of 7.10 M hydrobromic acid solution should be used to prepare 5.50 L of 0.400 M HBr
Alex73 [517]

Answer:

310 mL

Explanation:

Step 1: Given data

  • Initial concentration (C₁): 7.10 M
  • Initial volume (V₁): ?
  • Final concentration (C₂): 0.400 M
  • Final volume (V₂): 5.50 L

Step 2: Calculate the initial volume

We have a concentrated HBr solution and we want to prepare a diluted one. We can do so using the dilution rule.

C₁ × V₁ = C₂ × V₂

V₁ = C₂ × V₂ / C₁

V₁ = 0.400 M × 5.50 L / 7.10 M

V₁ = 0.310 L = 310 mL

Two atoms that are isotopes of one another must have the same number of what? Electrons, All Particles, Protons, or Neutrons
emmainna [20.7K]

atoms are made of 3 types of sub atomic particles; neutrons, protons and electrons

atomic number is the number of protons which is characteristic for the element. Atoms of the same element have the same number of protons.

mass number is the sum of the neutrons and protons.

Isotopes are atoms of the same element with different mass numbers. since they are the same element number of protons are the same but number of neutrons vary.

therefore 2 isotopes are of the same element so they have the same number of protons.
