Answer:
Density = 4.191 gm/L
Explanation:
Given:
Molar mass = 93.89 g/mol
Volume(Missing) = 22.4 L (Approx)
Find:
Density at STP
Computation:
Density = Mass/Volume
Density = 93.89 / 22.4
Density = 4.191 gm/L
Answer:
the answer is 55 cg/L
Explanation:
Knowing the conversions, there is 100 cg in one g. if there is .55 g/mL then you multiply by a 100 to get 55 cg/L.

Answer:
The mass of silver block = 73.95 g
Explanation:
Given,
For water:
Mass = 100.0 g
Initial temperature = 24.8 °C
Final temperature = 26.2 °C
Specific heat of water = 4.184 J/g°C
For silver:
Mass = x g
Initial temperature = 59.4 °C
Final temperature = 26.2 °C
Specific heat of water = 0.2386 J/g°C
Heat gain by water = Heat lost by silver
Thus,
Where, negative sign signifies heat loss
Or,
So,
<u>Hence, the mass of silver block = 73.95 g</u>
Answer:
A
Explanation:
The Charles law states that the volume of an ideal gas increases when temperature is increased under constant pressure. The pressure inside the balloon is always equal to the atmospheric pressure. Therefore answer A demonstrate the Charles law.
