What mass of chromium is found in a 13.28 g sample of Na_(2)CrO_(4) a 3.39 g Cr b 4.97g Cr C 1.90 g Cr d 4.26 g Cr

To determine the mass of chromium in a 13.28 g sample of , we need to follow these steps:1. Calculate the molar mass of .2. Determine the number of moles of in the sample.3. Calculate the mass of chromium in the sample.### Step 1: Calculate the Molar Mass of - Sodium (Na): 22.99 g/mol- Chromium (Cr): 51.996 g/mol- Oxygen (O): 16.00 g/mol ### Step 2: Determine the Number of Moles of in the Sample ### Step 3: Calculate the Mass of Chromium in the SampleEach mole of contains 1 mole of chromium. Therefore, the number of moles of chromium is also 0.082 moles. Therefore, the mass of chromium in the 13.28 g sample of is approximately 4.27 g.The closest answer to this calculation is:d) 4.26 g Cr
