Question

a 1.125 gram sample was found to contain 0.2456 grams of sodium oxalate. calculate the percentage of sodium oxalate in the sample and report the answer to the hundredths place with correct units.

Answer 1

The percentage of sodium oxalate in the sample is 21.84% w/w, calculated by dividing the mass of sodium oxalate by the total sample mass and multiplying by 100.

Step-by-step explanation:

The percentage of sodium oxalate in the sample can be calculated using the formula:

% of sodium oxalate = (Mass of sodium oxalate / Total sample mass) × 100%

Plugging in the given values:

% of sodium oxalate = (0.2456 g / 1.125 g) × 100% = 21.84%

Therefore, the percentage of sodium oxalate in the sample is 21.84% to the hundredths place with the correct units of %w/w (percent by weight).
