You are correct that the Relative Atomic Mass (RAM) was provided in the image but not used in the previous calculation. The reason RAM was not used to calculate $N$ (number of moles) in the previous step is because the formula $N = \frac{m}{\text{RAM}}$ requires the mass of the substance deposited ($m$), which was not given in the image. However, we can use the RAM to calculate the mass ($m$) of the substance deposited, now that we have calculated the number of moles ($N$). Given Values from the image and previous calculation: Number of moles ($N$) $\approx 0.0062176$ mol (from previous calculation) Relative Atomic Mass ($\text{RAM}$) = 119 g/mol Formula to calculate mass ($m$): $$m = N \times \text{RAM}$$ Step 1: Substitute the values into the formula. $$m = 0.0062176 \text{ mol} \times 119 \text{ g/mol}$$ Step 2: Calculate the mass ($m$). $$m \approx 0.7399 \text{ g}$$ Rounding to three significant figures: $$m \approx 0.740 \text{ g}$$ So, while RAM was not needed to find $N$ directly from current and time, it is essential to find the mass of the substance deposited. The mass of the substance deposited is approximately $\boxed{\text{0.740 g}}$.
