Question

question 1 (1 point) in the lab, you find the evaporating dish and watch glass have a mass of 43.1176 g. when you add your sample, the combined mass is 45.2006 g. what is the mass of your hydrated sample? a) 45.2006 g b) 2.0830 g c) 44.1591 g d) 2.10 g

Explanation:

Step1: Identify the formula

To find the mass of the sample, we use the formula: Mass of sample = Combined mass - Mass of dish and watch glass.

Step2: Substitute the values

Given, Mass of dish and watch glass = \( 43.1176 \, \text{g} \) and Combined mass = \( 45.2006 \, \text{g} \).
So, Mass of sample = \( 45.2006 - 43.1176 \)

Step3: Calculate the result

\( 45.2006 - 43.1176 = 2.0830 \, \text{g} \)

Answer:

B) 2.0830 g
