Answer:
0.6139M
Explanation:
A 3.50% by mass of NaCl means there are 3,50g of NaCl in 100g of solution. To find molarity we need to convert the mass of NaCl to moles and mass of solution to liters as follows:
<em>Moles NaCl -molar mass: 58.44g/mol-:</em>
3.50g NaCl * (1mol / 58.44g) = 0.05989 moles of NaCl
<em>Liters solution:</em>
100g solution * (1mL / 1.025g) * (1L / 1000mL) = 0.09756L of solution
<em>Molarity -Ratio of moles and liters-:</em>
0.05989 moles of NaCl / 0.09756L of solution =
<h3>0.6139M</h3>
This is a redox reaction/equation.
Zero degree celcius = 273.15 degree kelvin
Simply, to get the value of 45.1 degree celcius in kelvin, we will add 273.15 to the given value (45.1).
Degree in kelvin = 45.1 + 273.15 = 318.25 degree kelvin
Approximating to the nearest tenth, the value will be 318.3 degree kelvin
Answer:
It is a step by step process
