The number of potassium atom that are in 0.25 moles potassium carbonate is calculated as follows

by use of Avogadro contant

1 mole= 6.02 x10^23 atoms

what about 0.25 moles,
by close multiplication

{0.250 moles x 6.02 x10^23} / 1 mole = 1.505 x10^23 atoms

What is the scaling factor if the molar mass of

Step2247 [10]

Answer:

The scaling factor is 5.

Explanation:

Hello there!

In this case, since the scaling factor is defined as the ratio of the molar mass of the molecular formula (complete) to the empirical formula (simplified), it is possible to compute it for the empirical formula of CH2O whose molar mass is 30 g/mol (12+2+16) as shown below:

$sf=150/30=5$

Therefore, we can also infer that the molecular formula would be:

$C_5H_1_0O_5$

Best regards!
