Final answer:
To calculate the mass of the silicon block, convert the dimensions from centimeters to meters. Then, multiply the volume by the density of silicon.
Step-by-step explanation:
To calculate the mass of the block of silicon, we need to multiply the volume of the block by its density. First, we need to convert the dimensions of the block from centimeters to meters. The dimensions of the block are 0.021 m x 0.34 m x 1.18 m, which gives us a volume of 0.0089252 m³. Next, we multiply the volume by the density of silicon, which is 2.336 kg/m³. This gives us a mass of approximately 0.0208 kg or 20.8 grams.
