7. Which of the following represents the largest mass?
Tamiku [17]

Answer:

 10kg = 10 x 1000 = 10,000g

Explanation:

To know the quantity with the largest mass, we have to express all the units in grams:

for: 2 x 10mg = 2 x 10 x 10⁻³ = 0.02g

       0.001kg = 0.001 x 1000 = 1g

       1 x 10⁵ng = 1 x 10⁵ x 10⁻⁹ = 0.0001g

       2 x 10²cg = 2 x 10² x 10⁻² = 2g

       10kg = 10 x 1000 = 10,000g

Note:

              10⁻ ¹      deci(d)

              10⁻²       centi(c)

              10⁻³       milli(m)

            10⁻⁹         nano(n)

            10³           kilo(k)

Explain how you would calculate the q for warming 100.0 grams of liquid water from 0°C to 100 °C.
mojhsa [17]

Answer:

mass = 100 g

T1 = 0°C

T2 = 100 °C

C = 1 cal/g°C

Q = mC(T2 -T1)

Q = 100(1)(100 - 0)

Q = 100(100)

Q = 10000 cal
