Answer:
The molar mass of the liquid 62.89 g/mol
Explanation:
Step 1: Data given
Mass of the sample = 0.1 grams
Temperature = 70°C
Volume = 750 mL
Pressure = 0.05951 atm
Step 2: Calculate the number of moles
p*V = n*R*T
n = (p*V)/(R*T)
⇒ with n = the number of moles gas = TO BE DETERMINED
⇒ with p = The pressure = 0.05951 atm
⇒ with V = The volume of the flask = 750 mL = 0.750 L
⇒ with R = The gasconstant = 0.08206 L*atm/K*mol
⇒with T = the temperature = 70 °C = 343 Kelvin
n = (0.05951 *0.750)/(0.08206*343)
n = 0.00159 moles
Step 3: Calculate molar mass
Molar mass = mass / moles
Molar mass =0.1 gram / 0.00159 moles
Molar mass = 62.89 g/mol
The molar mass of the liquid 62.89 g/mol
A tsunami is a series of waves generated in an ocean
or other body of water by a disturbance such as an earthquake,
landslide, volcanic eruption, or meteorite impact. The picture at the
left shows how an earthquake can generate a tsunami in the overlying
water.
By washing away large surfaces of land and depositing it in a different area. Also does damage to structures and deposits salt into the soil.
Answer:
it has an equal number of neutrons and electrons
Explanation:
Number of protons always equal number of electron, but that's the case with a neutral atom. A neutral atom is an atom of any element that has no electric charge over it. This implies that it has same number of protons and electrons in it.
