Answer: Use the formula x = (c ÷ V) × 100 to convert the concentration (c) and volume (V) of the final solution to a percentage. In the example, c = 60 ml and V = 350 ml.

Explanation: Divide the mass of the solute by the total volume of the solution. Write out the equation C = m/V, where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution.

What amount of heat is removed to lower the temperature of 80 grams of water from 75º C to 45º C? The specific heat of liquid wa

Sindrei [870]

Answer:The correct answer option A.

Explanation:

$Q= m\times c\times \Delta T$

Q= heat removed from the water

m= mass of the water = 80 grams

c = heat capacity of water= 4.18 J/g°C

$\Delta T={\text{Change in temperature}}=45^oC-75^oC=-30^oC$

$Q=80g\times 4.18J/g^oC\times(-30^oC)$

Q = -10,032 joules $\approx$ -10,000 Joules

Negative sign indicates that heat was removed from the water.

Heat removed from the water of 80 gram of water is 10,032 Joules.Hence, the correct answer option A.

Perform the following mathematical operations and express the correct answer to the proper number of significant figures or deci

nordsb [41]

Answer: 7.71 + 4.31 + 1.7 + 4.00141= 17.72141

7.71 x 4.31 x 1.7 x 4.00141= 226.04433255

Explanation:

(i) 7.71 + 4.31 + 1.7 + 4.00141

= 7.71000+4.31000+1.70000+ 4.00141 [make like decimals]

= 17.72141 [By adding the corresponding places ]

(ii) 7.71 x 4.31 x 1.7 x 4.00141 =( 7.71 x 4.31) x 1.7 x 4.00141

= 33.2301 x 1.7 x 4.00141

= (33.2301 x 1.7) x 4.00141

= 56.49117 x 4.00141

= ( 56.49117 x 4.00141 )

= 226.04433255

Hence, 7.71 + 4.31 + 1.7 + 4.00141= 17.72141

7.71 x 4.31 x 1.7 x 4.00141= 226.04433255
