How many grams are in 4 moles of aluminum phosphate

Chemistry
2 answers:
Musya8 [376]4 years ago
6 0

Answer:

488g

Explanation:

First let us obtain the molar mass of aluminium phosphate (AlPO4)

This is illustrated below:

Molar Mass of AlPO4 = 27 + 31 + (16x4) = 27 + 31 + 64 = 122g/mol

Number of mole of AlPO4 = 4moles

Mass = number of mole x molar Mass

Mass of AlPO4 = 4 x 122 = 488g

The half life for the decay of radium is 1620 years what is the rate constant
Lilit [14]
Decay is a type of degradation reaction and thus is considered a first order reaction. thus the formula goes like this.
 
rate constant= 0.693/half life

so here...

rate constant= 0.693/1620 year^-1

How many molecules of propane were in the erlenmeyer flask? Avogadro's number is 6. 022 × 10^23 molecules/mol
Ede4ka [16]

3.74×10^{21}

3.74 ×10^{21} molecules of propane were in the erlenmeyer flask.

number of moles of propane can be calculated as moles of propane.

mass of propane =  0.274 g

molar mass of propane = 44.1

So this gives us the value of 6.21×10^{-3} moles of propane

No one mole of propane As a 6.0-2 × 10^{23}

so, 6.21 ×10^{-3} × 6. 022 × 10^23

= 3.74 ×10^{21}

Therefore, molecules of propane were in the erlenmeyer flask is found to be 3.74 ×10^{21}

<h3>What is erlenmeyer flask?</h3>
  • A laboratory flask with a flat bottom, a conical body, and a cylindrical neck is known as an Erlenmeyer flask, sometimes known as a conical flask or a titration flask.
  • It bears the name Emil Erlenmeyer after the German chemist.

<h3>What purpose does an Erlenmeyer flask serve?</h3>
  • Liquids are contained in Erlenmeyer flasks, which are also used for mixing, heating, chilling, incubating, filtering, storing, and other liquid-handling procedures.
  • For titrations and boiling liquids, their sloped sides and small necks make it possible to whirl the contents without worrying about spills.

If a reaction occurs when a piece of metal is placed in a solution, what can you conclude about the solution?
USPshnik [31]
Hello!

If a reaction occurs when a piece of metal is placed in a solution, you can conclude that the solution is <span>probably acidic because bases rarely react with metals.

Strong Acids, like HCl, react with metals to produce salts and release gaseous hydrogen (H</span>₂) which is evidenced by the generation of bubbles in the solution. The general chemical equation for this kind of reactions for a metal M and an acid HA is:

2M(s) + 2HA(aq) → 2MA(aq) + H₂(g)

Have a nice day!
