Answer:
36 mL of water can be displace by the 408 g lead
Explanation:
Given data:
Mass of lead = 408 g
Volume of water displaced by lead = ?
Solution:
The volume of water displace by the lead would be equal to the given volume of lead.
So we will calculate the volume from given mass of lead from density formula.
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Density of lead is 11.36 g/cm³.
d = m/v
11.36 g/cm³ = 408 g/ v
v = 408 g/ 11.36 g/cm³
v =36 cm³
1 cm³ = 1 mL
volume = 36 mL
36 mL of water can be displace by the 408 g lead.
Answer:
Explanation:
<u>1) Data:</u>
<em />
a) V = 75.0 liter
b) n = 15.82 mol
c) p = 546.8 kPa
d) T = ?
<u>2) Formula:</u>
- Ideal gas equation: pV = nRT
Where:
- n = number of moles
- V = volume
- p = absolute pressure
- T = absolute temperature
- R = Universal Gas constat: 8.314 kPa - liter / K-mol
<u>3) Solution:</u>
a) <u>Solve the equation for T</u>:
b) <u>Substitute and compute</u>:
- T = 546.8 kPa × 75.0 l iter / (15.82 mol × 8.314 kPa-liter/K-mol) = 312 K
(since the volume is expressed with 3 significant figures, the answer must show also 3 significant figures)
Answer:
The potential of energy availability at all locations where there is Sunlight
Explanation:
One advantage in owning a solar car is the potential of energy availability
The solar car source of energy is from the Sun which is readily available during the daytime where there is a clear sky. The energy from sunlight is converted to to electrical energy by the photovoltaic cells on solar panels installed on the roof area of solar powered cars
The energy from the Sunlight is a form of renewable energy and therefore allows for better stability as well as the possibility of reuse of the energy
There are no emissions from the use of solar cars including noise, making the solar car very environmentally friendly.
BaCI2 stands for Barium Chloride. Hope this helps!
