Answer:

0.052L

Explanation:

Molarity of a substance, which refers to the molar concentration, is calculated as follows:

Molarity (M) = number of moles (mol) ÷ volume (L)

Mole = mass ÷ molar mass

Molar Mass of AgNO3 since Ag = 108, N = 14, O = 16

108 + 14 + 16(3)

= 108 + 14 + 48

= 170g/mol

Mole = 21.89 g ÷ 170g/mol

Mole = 0.129moles

Using Molarity (M) = number of moles (mol) ÷ volume (L)

Volume = number of moles ÷ molarity

V = 0.129 ÷ 2.50

V = 0.0516

To the correct significant figure i.e. 4s.f, the numerical value of volume = 0.052L

-BARSIC- [3]
 7.22 moles of C2H6. Since there are 2 carbon atoms per C2H6, we must multiply the number of moles of C2H6 by 2 to get the number of moles of Carbon which is 14.4 or 14 if using two sig figs.

What bsic difference is between NMR and MS spectroscopic techniques?​
timama [110]

Answer:

The Nuclear magnetic resonance is the process this technique does not use radiation.

The  ms is an sensitive technology can be a massive number and small sample of the blood.

Explanation:

The Nuclear magnetic resonance we look at the both side of that coin.

The technique provides that fatty acid composition and various including amino acids.

These are contain the complementary these biomarkers, that are suitable for all kinds of studies. there are many types of research:-

(1) A powerful tool metabolic (2) A versatile tool research (3) Quick analysis (4) Low cost analysis.

The MS is an extremely sensitive technology using a very small number of the blood.

(1) Powerful techniques (2) Highly method (3) Large number of metabolites (4)Small sample volume

MS can be fine mapping metabolic pathways to sign analytical strategy.

Explain how you would calculate the q for warming 100.0 grams of liquid water from 0°C to 100 °C.
mojhsa [17]

Answer:

mass = 100 g

T1 = 0°C

T2 = 100 °C

C = 1 cal/g°C

Q = mC(T2 -T1)

Q = 100(1)(100 - 0)

Q = 100(100)

Q = 10000 cal
