Answer:
The equation for molarity is moles/liter for the first question you would do 0.256/0.143 liters to get 1.790 mol/L
Explanation:
The second problem you would do need to find the moles of NaCl which you would do by doing 4.89 g/58.44g/mol= 0.08367 then do 0.08367/0.600= 0.139 mol/L
The third problem would be the same steps as the second one.
The fourth problem would be (0.460M)(5.50L)= 2.53 moles

Answer:
![=2.0x10^4mg](https://tex.z-dn.net/?f=%3D2.0x10%5E4mg)
Explanation:
Hello there!
In this case, when performing units conversions involving two proportional factors we need to make sure we first convert to the base unit and then to the target one; thus, since 1 kg = 1000 g and 1 g = 1000 mg, we set up the following expression:
![=0.020kg*\frac{1000g}{1kg} *\frac{1000mg}{1g} \\\\=2.0x10^4mg](https://tex.z-dn.net/?f=%3D0.020kg%2A%5Cfrac%7B1000g%7D%7B1kg%7D%20%2A%5Cfrac%7B1000mg%7D%7B1g%7D%20%5C%5C%5C%5C%3D2.0x10%5E4mg)
