Answer:125.0964g
Explanation:
Density = mass/volume
Density = 2.7 gcm-3
Volume=2.7*1.2*14.3=46.332
Mass=?
Mass= density* volume
= 2.7× 46.332=125.0964g
The mass in grams of the aluminum bar is 125.1 g
From the question,
We are to determine the mass of the aluminum bar.
Mass can be calculated by using the formula,
Mass = Density × Volume
First, we will determine the volume of the aluminum bar.
From the given information,
The bar of aluminum measures 2.7 cm by 1.2 cm by 14.3 cm.
Thus, the volume
V = 2.7 cm × 1.2 cm × 14.3 cm
V = 46.332 cm³
Also, from the given information
Density of aluminum = 2.7 g/cm³
Putting the parameters into the formula, we get
Mass = 2.7 × 46.332
Mass = 125.0964 g
Mass ≅ 125.1 g
Hence, the mass in grams of the aluminum bar is 125.1 g
