Answer:
5
Explanation:
(2n+1 C + N - H - O)÷2=(9×2+2-10)÷2=5
Answer:
Explanation:
To convert from grams to moles we must use the molar mass, which is found on the Periodic Table.
Use the molar mass as a ratio.
Multiply by the given number of grams: 118
Flip the fraction so the grams of argon will cancel each other out.
The original measurement of grams had 3 significant figures, so our answer must have 3 sig figs.
For the number we calculated, that is the hundredth place. The 7 in the thousandth place tells us to round the 5 to a 6.
There are about <u>2.96 moles of Argon</u> in 118 grams.
The 3 domains are archaea, bacteria, and eukaryote. It is a biological classification.
