An oral solution has a dosage of 500 mg in 5 mL. If a 0.7 g dosage is required, how many mL must be given?

Physics

Answer:

7 mL

Explanation:

Given that:

mass of an oral solution = 500 mg

solution in mL = 5mL

Thus, the ratio = 5 mL/500 mg

= 0.01 mL/mg

since 1000 mg = 1g

∴

= 0.01 mL/mg × 1000 mg/1g

= 10 mL/g

Now, suppose the amount of 0.7 g dosage is required:

∴

the needed amount of mL will be:

= 10 mL/g × 0.7 g

= 7 mL

What is the mass of an object that has a weight of 110N ?
fgiga [73]
  • Weight (W) = 110 N
  • Acceleration due to gravity (g) = 9.8 m/s^2
  • Let the mass of the object be m.
  • By using the formula, W = mg, we get,
  • 110 N = 9.8 m/s^2 × m
  • or, m = 110 N ÷ 9.8 m/s^2
  • or, m = 11.2 Kg

<u>Answer:</u>

<em><u>The </u></em><em><u>mass </u></em><em><u>of </u></em><em><u>the </u></em><em><u>object </u></em><em><u>is </u></em><em><u>1</u></em><em><u>1</u></em><em><u>.</u></em><em><u>2</u></em><em><u> </u></em><em><u>Kg.</u></em>

Hope you could get an idea from here.

Juliette sets the initial velocity to +10 m/s, the acceleration to zero, and clicks “start.” How can Shakina describe the subseq
ICE Princess25 [194]

Explanation :

It is given that :

The initial velocity of the car is 10 m/s.

Juliette sets the acceleration to zero.

We know that, acceleration a=\frac{v-u}{t}\

where,

u is the initial velocity and v is the final velocity.

So, final velocity will become 10 m/s.

Hence, the car will move with the constant velocity i.e. 10 m/s.

So, Shakina described that the car will move with the constant velocity of 10 m/s as acceleration is zero.
