Question

how many bromine atoms are there in 4 molecules of ch₃br? hint: the symbol for bromine is br.

Explanation:

Step1: Analyze the formula of \( CH_3Br \)

In one molecule of \( CH_3Br \), the number of bromine (Br) atoms is 1 (from the chemical formula \( CH_3Br \), we can see there is 1 Br atom per molecule).

Step2: Calculate the number of Br atoms in 4 molecules

To find the number of Br atoms in 4 molecules of \( CH_3Br \), we multiply the number of Br atoms per molecule (1) by the number of molecules (4). So the calculation is \( 1\times4 = 4 \).

Answer:

4
