Question 3 (2 points) A student carried out this experiment and found: mass gelatin capsule(1.27x10n-1) g mass alloy sample + gelatin capsule = (2.784x10^-1) g mass empty beaker = (1.492x10^2) g mass beaker displaced water (2.900x10 2) g Temperature 294.15 K Barometric pressure 746 mm Hg vapor pressure of water = 18.65 mm Hg What was the mass of the alloy sample in grams? Enter your answer in scientific notation with three significant figures. Do not include any units in your answer. Note: The numbers in this problem are different from the numbers in the other problems. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10

Explanation / Answer

mass of gelatin capsule= 1.27x10-1 g

mass of alloy sample + gelatin capsule= 2.784x10-1 g

Hence the mass of alloy sample= (2.784x10-1 ) - (1.27x10-1 ) g= 1.514x10-1 g
