How many moles of each element are in one mole of Sr(HCO,),? (3 points)
O 1 mole of strontium, 1 mole of hydrogen, 1 mole of carbon, 5 moles of O
O1mole of strontium, 2 moles of hydrogen, 2 moles of carbon, 6 moles of O
O 2 moles of strontium, 2 moles of hydrogen, 2 moles of carbon, 5 moles of O
O2 moles of strontium, 2 moles of hydrogen, 2 moles of carbon, 6 moles of O

Sagot :

Answer: 1 mole of strontium, 2 moles of hydrogen, 2 moles of carbon, 6 moles of O

Explanation: i think i’m not sure

A mole corresponds to the mass of a substance that contains particles of the substance.

The concept of moles are used in various ways:-

  • Chemical equation.
  • Law of constant proportion.

According to the question, the formula required is:-

[tex]n=\frac{Number\ of\ molecules}{na}[/tex]

The Na is defined as the Avogadro constant is the proportionality factor that relates the number of constituent particles in a sample with the amount of substance in that sample.

According to the question, the compound is [tex]Sr(HCO_{3})_{2}[/tex].

Hence the correct option is 2, that is 1 mole of strontium, 2 moles of hydrogen, 2 moles of carbon, 6 moles of oxygen.
