What is the difference between an empirical formula and a molecular formula?

1 answer:

7 0

Answer:

The empirical formula simply states the ratios of the elements that make up the molecule, while molecular formulas specify the amounts of each element exactly, not just giving the ratio. Let's take ethane (C2H6) as an example.

You have 2.9 x 10^24 atoms of calcium How many grams do you have?

fomenos

Answer:

a mole of calcium is 6.02 ×10²³, therefore 2.9 ×10²⁴ will be ~4.82moles,

And since a mole of calcium is 40.1g

4.82 moles will be 4.82 × 40.1

that's =193.28g

Answer:

$T_2=335.42K=62.27^oC$

Explanation:

Hello,

In this case, by using the general gas law, that allows us to understand the pressure-volume-temperature relationship as shown below:

$\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}$

Thus, solving for the temperature at the end (considering absolute units of Kelvin), we obtain:

$T_2=\frac{P_2V_2T_1}{P_1V_1}=\frac{1.8L*0.75atm*(25+273.15)K}{1.2L*1.0atm} \\\\T_2=335.42K=62.27^oC$

Best regards.
