1.20 x 10^22 molecules NaOH to gram

Trava [24]

Answer:

$\boxed {\boxed {\sf 0.797 \ g \ NaOH}}$

Explanation:

1. Convert Molecules to Moles

First, we must convert molecules to moles using Avogadro's Number: 6.022*10²³. This tells us the number of particles in 1 mole of a substance. In this case, the particles are molecules of sodium hydroxide.

$\frac {6.022*10^{23} \ molecules \ NaOH} {1 \ mol \ NaOH}}$

Multiply by the given number of molecules.

$1.20*10^{22} \ molecules \ NaOH *\frac {6.022*10^{23} \ molecules \ NaOH} {1 \ mol \ NaOH}}$

Flip the fraction so the molecules cancel out.

$1.20*10^{22} \ molecules \ NaOH *\frac {1 \ mol \ NaOH} {6.022*10^{23} \ molecules \ NaOH}}$

$1.20*10^{22} *\frac {1 \ mol \ NaOH} {6.022*10^{23}}}$

$\frac {1.20*10^{22} \ mol \ NaOH} {6.022*10^{23}}}$

$0.0199269345732 \ mol \ NaOH$

2. Convert Moles to Grams

Next, we convert moles to grams using the molar mass.

We must calculate the molar mass using the values on the Periodic Table. Look up each individual element.

Na: 22.9897693 g/mol
O: 15.999 g/mol
H: 1.008 g/mol

Since the formula has no subscripts, we can simply add the molar masses.

NaOH: 22.9897693+15.999+1.008=39.9967693 g/mol

Use this as a ratio.

$\frac {39.9967693 \ g \ NaOH }{1 \ mol \ NaOH}$

Multiply by the number of moles we calculated.

$0.0199269345732 \ mol \ NaOH*\frac {39.9967693 \ g \ NaOH }{1 \ mol \ NaOH}$

The moles of sodium hydroxide cancel.

$0.0199269345732 *\frac {39.9967693 \ g \ NaOH }{1}$

$0.0199269345732 *39.9967693 \ g \ NaOH$

$0.79701300498 \ g \ NaOH$

The original measurement of molecules has 3 significant figures, so our answer must have the same. For the number we calculated, that is the thousandth place. The 0 tells us to leave the 7 in the hundredth place.

$0.797 \ g \ NaOH$

1.20*10²² molecules of sodium hydroxide is approximately 0.797 grams.

If adp (two phosphates) were hydrolyzed to amp, how would you expect this reaction to compare with the hydrolysis of atp to amp?

boyakko [2]

If ADP (two phosphates) were hydrolyzed to AMP, how would you expect this reaction to compare with the hydrolysis of ATP to AMP?

ADP and ATP are both hydrolyzed to give AMP, the only difference remains in the side product formed which is pyrophosphate for ATP hydrolysis and inorganic phosphate for ADP hydrolysis.

What is ATP hydrolysis?

Adenosine triphosphate (ATP) contains highly energetic phosphoanhydride bonds that, when broken, such as occurs in muscles, release chemical energy through a catabolic reaction process called ATP hydrolysis. Adenosine diphosphate (ADP) and an inorganic phosphate are the end result (Pi). Adenosine monophosphate (AMP), energy, and another inorganic phosphate can all be produced by further hydrolyzing ADP (Pi). The final step in the energy chain from food or sunlight to useful work like muscle contraction, the creation of electrochemical gradients across membranes, and life-sustaining biosynthetic processes is ATP hydrolysis.

ATP + H 2 O → AMP + Pyrophosphate(PP)ADP + H 2 O → AMP + Inorganic Phosphate(Pi)

Thus, ADP and ATP are both hydrolyzed to give AMP, the only difference remains in the side product formed which is pyrophosphate for ATP hydrolysis and inorganic phosphate for ADP hydrolysis.
