Answer:

The correct answer is mass = 48g

Explanation:

Hello!

Let's solve this!

The data is:

volume: 30.0 ml

density: 1.60 g / ml

The density formula is:

density = mass / volume

From this formula we cleared the mass:

mass = density * volume

mass = (1.6g / ml) * 30ml = 48g

We conclude that the correct answer is mass = 48g

Differentiating Star Clusters
Maru [420]

“Star cluster” is a generic way for astronomers to refer to a group of stars that formed from the same material and are gravitationally bound for at least some period of time. There are two major types of star clusters — globular clusters and open clusters — and they are actually quite different.

For many years after they were discovered, it was believed that the noble gases could not form compounds. Now we know that belie
Gala2k [10]

Answer:We are already given with the mass of the Xe and it is 5.08 g. We can calculate for the mass of the fluorine in the compound by subtracting the mass of xenon from the mass of the compound.

 mass of Xenon (Xe) = 5.08 g

 mass of Fluorine (F) = 9.49 g - 5.08 g = 4.41 g

Determine the number of moles of each of the element in the compound. 

   moles of Xenon (Xe) = (5.08 g)(1 mol Xe / 131.29 g of Xe) = 0.0387 mols of Xe

  moles of Fluorine (F) = (4.41 g)(1 mol F/ 19 g of F) = 0.232 mols of F

The empirical formula is therefore,

     Xe(0.0387)F(0.232)

Dividing the numerical coefficient by the lesser number.

    XeF₆

When 131.0 mL of water at 26.0°C is mixed with 81.0 mL of water at 85.0°C, what is the final temperature? (Assume that no heat i
JulsSmile [24]

Answer:

63.52°C is the final temperature

Explanation:

1) 131.0 mL of water at 26.0°C

Mass of water = m

Volume of the water =131.0 mL

Density of the water = 1.00 g/mL

Density=1.00 g/mL=\frac{m}{131.0 mL}

m = 131.0 g

Initial temperature of the water = T_i = 26.0°C

Final temperature of the water = T_f

Change in temperature ,\Delta T=T_f-T_i

Heat absorbed 131.0 g of water = Q

Q=m\times c\times \Delta T

2) 81.0 mL of water at 85.0°C

Mass of water = m'

Volume of the water =81.0 mL

Density of the water = 1.00 g/mL

Density=1.00 g/mL=\frac{m'}{81.0 mL}

m' = 81.0 g

Initial temperature of the water = T_i' = 85.0°C

Final temperature of the water = T_f'

Change in temperature ,\Delta T'=T_f'-T_i'

Heat lost by 81.0 g of water = Q'

Q'=m'\times c\times \Delta T'

After mixing both liquids the final temperature will become equal fro both liquids.

T_f=T_f'

Since, heat lost by the water at higher temperature will be equal to heat absorbed by the water at lower temperature.

Q=-Q' (Law of conservation of energy.)

Let the specific heat of water be c

m\times c\times \Delta T=m'\times c\times \Delta T'

131.0 g\times c(T_f-26^oC)=-(81.0.0 g\times c(T_f-85^oC))

T_f=63.52^oC

63.52°C is the final temperature
