Convert 554 K/s into μK/ms in this problem all I need to know is what does the K is?
laila [671]

Answer:

5,54x10⁵μK/ms

Explanation:

To solve this problem you don't need to know what the K is.

You need to know what mean SI prefixes. These prefixes are added at the beginning of an unit to make a new unit. For example a kilometer means 1000 meters, a miligram means 0,001 grams.

In this problem you have 554 K per s. 554K are:

554 K ×\frac{1 micro}{1x10^{-6}} = 5,54x10⁸ μK

1 s are:

1s ×\frac{1 m}{1x10^{-3}} = 1000 ms

Thus 554 K/s are 5,54x10⁸ μK/ 1000 ms = <em>5,54x10⁵μK/ms</em>

I hope it helps!

An unknown liquid has a mass of 30.8 g, and a volume of 31.5 mL. What is the density of this liquid?
julsineya [31]

The density of the liquid is 0.98 g/mL

<h3>What is density? </h3>

The density of a substance is defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as:

Density = mass / volume

With the above formula, we can obtain the density of the liquid.

<h3>How to determine the density </h3>
  • Mass = 30.8 g
  • Volume = 31.5 mL
  • Density =?

Density = mass / volume

Density of liquid = 30.8 / 31.5

Density of liquid = 0.98 g/mL
