Determine the number of grams of sodium carbonate needed to prepare 100.0 ml of a 2.5 m solution
SCORPION-xisa [38]

Answer:

26.5 g

Explanation:

First we convert 100.0 mL to L:

  • 100.0 mL / 1000 = 0.100 L

Now we <u>calculate how many moles of sodium carbonate are needed</u>, using the <em>definition of molarity</em>:

  • Molarity = moles / liters
  • moles = molarity * liters
  • 2.5 M * 0.100 L = 0.25 mol

Finally we <u>convert 0.25 moles of sodium carbonate into grams</u>, using its <em>molar mass</em>:

  • 0.25 mol * 106 g/mol = 26.5 g

How volcanoes are created​
Lera25 [3.4K]

A volcano is created when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Hot ash and gases are thrown into the air.
