sci9 density practice name: 1. a student measures the mass of an 8 cm³ block of brown sugar to be 12.9 g. what is the density of the brown sugar? 2. a chef fills a 50 ml container with 43.5 g of cooking oil. what is the density of the oil?
Answer
Explanation:
Step1: Recall density formula
$\rho=\frac{m}{V}$
Step2: Calculate density of brown sugar
$\rho_1=\frac{12.9\ g}{8\ cm^{3}} = 1.6125\ g/cm^{3}$
Step3: Calculate density of oil
$\rho_2=\frac{43.5\ g}{50\ mL}=0.87\ g/mL$
Answer:
- $1.6125\ g/cm^{3}$
- $0.87\ g/mL$
