Solubility at 100 °C = 480 g / 100 mL of solution =: saturated solution
The proportion 240 g / 50 mL is equal to the saturated ratio 480 g / 100 mL
Then, 240 g of sugar in 50 mL of boiling water will make a saturated solution.
Answer: saturated
Answer:
here
Explanation:
This is the electron configuration of the element carbon.
Answer: 6.0 g of silicon has more atoms
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
of particles.
To calculate the moles, we use the equation:
![\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20moles%7D%3D%5Cfrac%7B%5Ctext%7BGiven%20mass%7D%7D%7B%5Ctext%20%7BMolar%20mass%7D%7D)
a) ![\text{Number of moles of silicon}=\frac{6.0g}{28g/mol}=0.21moles](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20moles%20of%20silicon%7D%3D%5Cfrac%7B6.0g%7D%7B28g%2Fmol%7D%3D0.21moles)
1 mole of Si contains =
atoms
0.21 moles of Si contains =
atoms
b) ![\text{Number of moles of iron}=\frac{6.0g}{56g/mol}=0.11moles](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20moles%20of%20iron%7D%3D%5Cfrac%7B6.0g%7D%7B56g%2Fmol%7D%3D0.11moles)
1 mole of Fe contains =
atoms
0.11 moles of Fe contains =
atoms
Thus 6.0 g of silicon has more atoms
<span>8.278 g/mL
The definition of density is mass per volume. So what you need to do is divide the known mass by the known volume. So
1.663 g / 0.2009 mL = 8.27775 g/mL
But you also have to keep track of significant figures. Since both 1.663 and 0.2009 have 4 significant figures each, you need to round the result to 4 significant figures. So
8.27775 g/mL = 8.278 g/mL</span>
