molecular weight of NH3 or grams This compound is also known as Ammonia. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles NH3, or 17.03052 grams.
Answer:
4.5 kilograms of silicon dioxide is required to produce 3.00 kg of SiC.
Explanation:
The balanced equation for the reaction between silicon dioxide and carbon at high temperature is given as:
![SiO_2+3C\rightarrow SiC+2CO](https://tex.z-dn.net/?f=SiO_2%2B3C%5Crightarrow%20SiC%2B2CO)
1 mole silicon dioxide reacts with 3 moles of carbon to give 1 moles of silicon carbide and 2 moles of carbon monoxide.
Mass of SiC = 3.00kg = 3000.00 g
1 kg = 1000 g
Molecular mass of SiC = 40 g/mol
Moles of SiC = ![\frac{3000.00 g}{40 g/mol}= 75 mol](https://tex.z-dn.net/?f=%5Cfrac%7B3000.00%20g%7D%7B40%20g%2Fmol%7D%3D%2075%20mol)
According to reaction, 1 mole of SiC is produced from 1 mole of silicon dioxide.
Then 75 moles of SiC will be produce from:
of silicon dioxide.
mass of 75 moles of silicon dioxde:
![75 mol\times 60 g/mol=4500 g=4.5 kg](https://tex.z-dn.net/?f=75%20mol%5Ctimes%2060%20g%2Fmol%3D4500%20g%3D4.5%20kg)
4.5 kilograms of silicon dioxide is required to produce 3.00 kg of SiC.
