To calculate the ratio of sodium (Na) to element "Z" in compound A, follow these steps:

1. Identify the Given Data:
- Mass of sodium (Na) in compound A: [tex]\(12.00 \, \text{grams}\)[/tex]
- Mass of element Z in compound A: [tex]\(2.44 \, \text{grams}\)[/tex]

2. Set Up the Ratio:
The ratio of sodium to element Z is given by the mass of sodium divided by the mass of element Z.

3. Calculate the Ratio:
[tex]\[ \text{Ratio of Na to Z} = \frac{\text{Mass of Na in Compound A}}{\text{Mass of Z in Compound A}} \][/tex]
Substitute the given values:
[tex]\[ \text{Ratio of Na to Z} = \frac{12.00 \, \text{grams}}{2.44 \, \text{grams}} \][/tex]

4. Perform the Division:
[tex]\[ \text{Ratio of Na to Z} = 4.918032786885246 \][/tex]

Hence, the ratio of sodium to element "Z" in compound A is approximately [tex]\(4.92:1\)[/tex].
