Explanation:

We need to convert 42.0 microliters into liters. Liters and microliters are the units to find the volume. Volume is the space occupied by an object. We must know 1 micro equals to what. So,

$1\ \mu =10^{-6}$

So,

$42\ \mu L=42\times 10^{-6}\ L$

So, there are $42\times 10^{-6}\ L$ in 42 microliters.

Isobars: Ca-41, K-41 and Ar-41

Part b:

Number of proton

Part c:

Incorrect statement

Explanation:

Part a:

Nuclei with same mass number are called isobars.

Given:

Ca-40, Ca-41, K-41 and Ar-41

Ca-41, K-41 and Ar-41 have equal mass numbers, so these are isobars.

Part b:

Atomic number of Ca = 20

Atomic no. = Number of proton.

So, Ca-40 ans C-41 have same number of proton or in other words proton count is common in both.

Part c:

Number of neutrons in Ca-41

Atomic number = 20

Mass number = 41

Number of neutron = Mass number -atomic number

= 41 -20 = 21

Number of neutrons in K-41

Atomic number = 19

Mass number = 41

Number of neutron = Mass number -atomic number

= 41 -19 = 22

Number of neutrons in Ar-41

Atomic number = 18

Mass number = 41

Number of neutron = Mass number -atomic number

= 41 -18 = 23

So, the statement is incorrect.

MArishka [77]

Answer:

1.0 × 10⁻⁵ mol/L

Explanation:

The concentration of a gas (C) in a liquid depends on its partial pressure (P), as expressed in Henry's law.

C = k × P

where,

k is the henry's law constant

When the partial pressure of the gas equilibrates at 3.0 × 10⁻⁴ atm, its concentration in the liquid is:

C = k × P

C = 3.4 × 10⁻² mol/L.atm × 3.0 × 10⁻⁴ atm

C = 1.0 × 10⁻⁵ mol/L

What is volume (chemistry definition)

krok68 [10]

Answer:

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using SI derived unit, the cubic meter.
