Concept:
Quadrants and Signs: The sine function is positive in the first and second quadrants and
negative in the third and fourth quadrants.
Mathematical Calculation:
1. Locate 300°: An angle of 300° lies in the fourth quadrant.
2. Find the reference angle: The reference angle for 300° is 360° - 300° = 60°.
3. Determine the sign: Since 300° is in the fourth quadrant, where the sine function is
negative, sin(300°) will be negative.
4. Evaluate: We know that sin(60°) = √3/2. Therefore, sin(300°) = sin(360-60°) = -sin(60°)= -
√3/2

The value of sin(300°) is

Explain : add two measurements, L and B, and express the result with the correct number of
significant figures.
Concept : Significant figures are the digits in a number that are considered reliable and
contribute to the number's precision.
Addition with Significant Figures: When adding or subtracting measurements, the result
should be rounded to the same number of decimal places as the measurement with the least
decimal places.
Formula : L + B = Sum
Calculation : L + B = 3.331 cm + 3.1 cm = 6.431 cm
L has three decimal places.B has one decimal place.
The result should have the same number of decimal places as the measurement with the least
decimal places, which is one.
Round 6.431 cm to one decimal place, which gives 6.4 cm.
Ans (3) 6.4 cm
Difficulty level : easy

40) 6.67 × 10–11


order of magnitude = –11 + 1

A. Moles of CO2 = Volume of CO2 / Molar volume at STP
B. Moles of CO2 = 2.24 L / 22.4 L/mol = 0.1 mol
B. Determine moles of CaCO3 reacted:
A. From the balanced equation: CaCO3 → CaO + CO2
B. 1 mole of CaCO3 produces 1 mole of CO2
C. Therefore, moles of CaCO3 reacted = moles of CO2 = 0.1 mol
C. Calculate mass of CaCO3 reacted:
A. Mass of CaCO3 reacted = Moles of CaCO3 reacted * Molar mass of CaCO3
B. Mass of CaCO3 reacted = 0.1 mol * 100.09 g/mol = 10.01 g
D. Calculate percentage purity of CaCO3:
A. Percentage purity = (Mass of CaCO3 reacted / Mass of sample) * 100
B. Percentage purity = (10.01 g / 50 g) * 100 = 20.02%

5. Final Answer:

A. The percentage purity of CaCO3 in the sample is 20.02%.
