If a person takes 30 ml of vinegar a day and the molarity of the vinegar is 0. 84 m then how many grams of acetic acid (hc2h3o2
babunello [35]

The mass of the acetic acid is 1.512 g.

<h3 /><h3>What is Molarity?</h3>

molarity is the concentration of a substance in mol per dm³

From the question,

The number of moles contained in the 30 mL vinegar is

  • n = (0.84×30)/1000
  • n = 0.0252 mol.

the molar mass of vinegar is calculated below.

  • m.m of (HC₂H₃O₂) = [1+(12×2)+(1×3)+(16×2)]
  • m.m = (1+24+3+32]
  • m.m = 60 g/mol.

To calculate the mass of acetic acid, we use the formula below.

  • R.m = n×m.m............. Equation 1

Where

  • R.m = mass of acetic acid.

Substitute these values into equation 1

  • R.m = (0.0252×60)
  • R.m = 1.512 g.

Hence, The mass of the acetic acid is 1.512 g.

How is the size of a planet related to the thickness of its atmosphere
adoni [48]

Mainly, the mass of a planet doesn't matter, considering many planets are made up of gas, and how in different situations, atmospheres can be destroyed (The Sunburnt off Mercury's Atmosphere). However, in some cases, the planet can be in a good situation on the galactic map and have great conditions for an atmosphere, such as Earth. In which case, the mass of an object can attract a smaller object, causing gravity. Therefore, the bigger the mass of a planet when in right and specific conditions, the more atmosphere it can attract, if there is any floating by the planet.

If it is bigger it will have more gravitational influence and therefore gather more gases.
