What is the mass of a glucose solution that fills a 0.500-L intravenous bottle if the density of the glucose solution is

____ [38]

Answer:

m = 575 g

Explanation:

Given data:

Volume of solution = 0.500 L (0.500×1000 = 500 mL)

Density of glucose solution = 1.15 g/mL

Mass of glucose solution = ?

Solution:

Formula:

d = m/v

d = density

m = mass

v = velocity

Now we will put the values in formula.

1.15 g/mL = m/500 mL

m = 1.15 g/mL × 500 mL

m = 575 g

A sample of nickel is heated to 99.8 degrees C and placed in a coffee cup calorimeter containing 150.0g water at 23.5 degrees C.

vesna_86 [32]

<u>Answer:</u> The mass of nickel that was originally heated is 28.4 grams.

<u>Explanation:</u>

When metal is dipped in water, the amount of heat released by metal will be equal to the amount of heat absorbed by water.

$Heat_{\text{absorbed}}=Heat_{\text{released}}$

The equation used to calculate heat released or absorbed follows:

$Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})$

$m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]$ ......(1)

where,

q = heat absorbed or released

$m_1$ = mass of nickel = ?

$m_2$ = mass of water = 150.0 g

$T_{final}$ = final temperature = 25.0°C

$T_1$ = initial temperature of nickel = 99.8°C

$T_2$ = initial temperature of water = 23.5°C

$c_1$ = specific heat of nickel = 0.444 J/g°C

$c_2$ = specific heat of water= 4.186 J/g°C

Putting values in equation 1, we get:

$m_1\times 0.444\times (25.0-99.8)=-[150.0\times 4.186\times (25.0-23.5)]$

$m_1=28.4g$

Hence, the mass of nickel that was originally heated is 28.4 grams.

The net force on an object that is accelerating at a rate of 4 m/sec is 255 N. What is the mass of the object in kg?

aleksklad [387]

Answer:

Given - acc = 4 m/ s^2

Force = 255 N

To find = mass

Solution -

Using the formula,

$f = m \times a$

255 = Mass × 4

255 /4 = Mass

63.75 = Mass

1 N = kg m/s^2

63.75 kg = Mass
