Answer:

d. Cooling & Crystallization

Explanation:

One of the stages of the rock cycle that can take place under mere hours or days is cooling and crystallization.

Cooling and crystallization of lava on the earth surface is a very rapid and fast process.

When magma from within the earth reaches the surface, it becomes lava. Due to the nature of the surface, it cools rapidly and very fast to form very fine grained igneous rocks.

Gas has a volume of 247.3 ML and is at 100 Celsius and 745 Hg. If the mass of the gas is 0.347 g what is the molar mass of the v
Ahat [919]

Answer:

The molar mass of the vapor is 43.83 g/mol

Explanation:

Given volume of gas = V = 247.3 mL = 0.2473 L

Temperature = T = 100^{\circ}C = 373 K

Pressure of the gas = P = 745 mmHg  (1 atm = 760 mmHg)

P = \displaystyle \frac{745}{760} \textrm{ atm} = 0.9802 \textrm{ atm}

Mass of vapor = 0.347 g

Assuming molar mass of gas to be M g/mol

The ideal gas equation is shown below

\textrm{PV} =\textrm{nRT} \\\textrm{PV} = \displaystyle \frac{m}{M}\textrm{ RT } \\0.98026 \textrm{ atm}\times 0.2473 \textrm{ L} = \displaystyle \frac{3.47 \textrm{ g}}{M}\times 0.0821 \textrm{ L.atm.mol}^{-1}.K^{-1}\times 373\textrm{K} \\M = 43.834 \textrm{ g/mol}

The molar mass of the vapor comes out to be 43.834 g/mol

An empty beaker weighs 20g and when filled with kerosene weighs 60g. If the volume of the kerosene is 15cm3, calculate the densi
oee [108]

Answer:

2.7 g/cm³

Explanation:

Step 1: Calculate the mass of kerosene

The mass of the full beaker (mFB) is equal to the sum of the masses of the empty beaker (mEB) and the mass of the kerosene (mK).

mFB = mEB + mK

mK = mFB - mEB

mK = 60 g - 20 g = 40 g

Step 2: Calculate the density of kerosene

Density (ρ) is an intrinsic property of matter. It can be calculated as the quotient between the mass of kerosene and its volume.

ρ = m/V

ρ = 40 g/15 cm³ = 2.7 g/cm³
