Which of the following are acceptable ways to make one liter of 1 M NaCl?

RSB [31]

Initially, weigh the correct amount of $NaCl$ calculated from the formula.

Number of moles = $\frac{Given mass in g}{Molar mass}$

As 1 mole of $NaCl$ is given and molar mass of $NaCl$ is $58.44 g/mol$ , then

1 mole of $NaCl$ = $\frac{Given mass in g}{58.44 g/mol}$

Mass of $NaCl$ in g = ${58.44 g}$

Thus,

1 mole of $NaCl$ = 58.44 g.

Now, the weighed amount of $NaCl$ i.e. 58.44 g is added to a 1 liter container and then add small amount of water in the container to dissolve the salt. After that, fill the container with distilled water to the graduation mark or until the total volume reaches 1 liter.

Thus, option (c) is correct i.e. first put one mole of salt in the container then add the water with stirring till the total volume reaches 1 liter.

How many atoms are there in each of the following ?a.)1.50 mol Na c.) 0.250 mol. Sib.)6.755 mol Pb

tamaranim1 [39]

$a) \: n = \frac{N}{NA} \\ 1.5 = \frac{x}{6.02 \times \: {10}^{23} } \\ x = 1.5 \times 6.02 \times {10}^{23} \\ x = 9.03 \times {10}^{23} \: atoms \: of \: Na$

$b) \: n = \frac{N}{NA} \\ 0.25 = \frac{x}{6.02 \times \: {10}^{23} } \\ x = 0.25 \times 6.02 \times {10}^{23} \\ x = 1.505 \times {10}^{23} \: atoms \: of \: Si \:$
$c) \: n = \frac{N}{NA} \\ 6.755 = \frac{x}{6.02 \times \: {10}^{23} } \\ x = 6.755 \times 6.02 \times {10}^{23} \\ x = 40,6651 \times {10}^{23} \\ x = 4.07 \times {10}^{24} \: atoms \: of \: Pb \:$

(35 points) ROCK TYPES. If you help me with this I'll love you forever

4vir4ik [10]

There are so many rock types around! Though, with all the rock types.. there are a few that we study within grade school and such. These types of rocks are,

-Igneous // Igneous rock is formed through the cooling and solidification of magma or lava.

-Sedimentary // Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface.

-Metamorphic // The original rock is subjected to heat and pressure, causing profound physical or chemical change.
