Answer:
Explanation:
Use Avogadro’s number to convert formula units of RbNO₃ to moles of RbNO₃.
1 mol RbNO₃ ≡ 6.022 × 10²³ formula units RbNO₃
Moles of RbNO₃ = 2.41 ×1 0²⁴ × = 4.00 mol RbNO₃
There are of RbNO₃ in 2.41 × 10²⁴ formula units.
Here's how you would solve it. The process should be the same for the others.
The answer to your question is C
Answer:
False
The ester functional group is not symbolized as R-C-R
Explanation:
The general formula of ester functional group is RCOOR′ where R represents a hydrogen atom or aryl group or an alkyl group while R' represents the alkyl group or an aryl group
Hence, the given statement is false
