<u>Answer:</u> The correct option is C) 1.68 mol/L

<u>Explanation:</u>

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

\text{Molarity of solution}=\frac{\text{Given mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (L)}} .....(1)

Given values:

Given mass of C_6H_{12}O_6 = 150 g

Molar mass of C_6H_{12}O_6 = 180 g/mol

Volume of the solution = 0.50 L

Putting values in equation 1, we get:

\text{Molarity of solution}=\frac{150}{180\times 0.50}\\\\\text{Molarity of solution}=1.68M

Hence, the correct option is C) 1.68 mol/L

Indicate the number of significant figures in the measured number 5.80
levacccp [35]

<u>Answer:</u>

The correct answer option is C. 3.

<u>Explanation:</u>

We are given the number '5.80' and we are to indicate the number of significant figures in the given measured number.

According to the rules of significant figures, numbers that are non-zero, zeros between any two significant numbers and the ending zeros in the decimal position are categorized as significant figures.

Therefore, the number 5.80 has 3 significant figures in it.

Begin by writing formulas for the reactants and products, including physical states. When necessary use coefficients to balance
xz_007 [3.2K]

Answer:

NaH(s) + H2O(l) ------> NaOH(aq) + H2(g)

2Al(s) + 3Cl2(g) -----> 2AlCl3(s)

Explanation:

The rule of thumb in balancing chemical reaction equation is that the number of atoms of each element on the reactant side must be the same as the number of atoms of the same element on the product side. Only then can any reaction equation be seen as balanced.

For example there are two aluminum atoms on both sides of the reaction equation and six chlorine atoms on both sides of the reaction equation. Hence the reaction equation is balanced.

Importancia de las soluciones acuosas y su CONTAMINACIÓN
vova2212 [387]
En una solución acuosa donde el agua es el solvente, el soluto que será disuelto por el agua tiene menos partículas, lo que hace que las partículas se muevan en un movimiento aleatorio. El agua pura tiene una baja concentración de iones y, por lo tanto, no conduce electricidad.
