Answer: True.
Explanation:
Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.
The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.
For example, the molar mass of NaCl can be calculated for finding the atomic mass of sodium (22.99 g/mol) and the atomic mass of chlorine (35.45 g/mol) and combining them. The molar mass of NaCl is 58.44 g/mol.
B.) Digestion
when food passes through the gastrointestinal tract, the food get mixed with digestive juices which break down large food molecules. The body absorbs these molecules/nutrients through the small intestine and enter your blood stream. Your blood stream delivers these nutrients to the rest of the body.
Answer:
Argon
Explanation:
Given data
We can find the molar mass (M) of the gas using the ideal gas equation.
P × V = n × R × T
P × V = m/M × R × T
M = m × R × T/P × V
M = 27.1 g × (0.08206 atm.L/mol.K) × 449 K/ 0.500 atm × 50.0 L
M = 39.9 g/mol
If the gas is monoatomic, the one with a molar mass of 39.9 g/mol is argon.
Phosphorus hope this helps :)
There is an extra pair of electrons bound to the central oxygen. This set of electrons repels against the other electrons surrounding the outside oxygen molecules, compressing the bond angle more than if another atom were present in its place. The actual angle size is around 116 degrees, noticeably smaller than the 120 degrees present in a trigonal planar structure.
