Answer and explanation:
The mole ratio for Mg and MgO would be 2:2 or 1:1 because Mg has 2 as a coefficient and so does MgO, which is why you can simplify the ratio to 1:1
The mole ratio for O and MgO would be 1:2 because O has 1 as the coefficient and MgO has 2 as a coefficient.
Answer:
0.350 g of iron
Explanation:
Step 1: Given data
Mass of iron (m): 350 mg
Step 2: Convert the mass of iron to milligrams
In order to convert the mass of iron from grams to milligrams we need a conversion factor. In this case, the conversion factor is 1 g = 1,000 mg.
350 mg Fe × 1 g Fe/1,000 mg Fe = 0.350 g Fe
350 milligrams of iron is equal to 0.350 grams of iron. We conserve the 3 significante figures of the original data.

please mark this answer as brainlest i got the answer from someone by the way which is my sis
but forget all of that
please mark brainlest
need 0.500 x 0.125 = 0.0625 moles of NaOH. The molecular weight is 23+16+1 = 40, so 0.0625 x 40 = 2.5 grams will do the trick.
