Bluetooth operates at frequencies between 2402 and 2480 MHz, or 2400 and 2483.5 MHz including guard bands 2 MHz wide at the bottom end and 3.5 MHz wide at the top. This is in the globally unlicensed (but not unregulated) Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency band.
The conversion between the two is 1000 kg/m3 to 1 g/cm3. Water never has an absolute density because its density varies with temperature. Water has its maximum density of 1g/cm3 at 4 degrees Celsius. When the temperature changes from either greater or less than 4 degrees, the density will become less then 1 g/cm3. Water has the maximum density of 1 g/cm3 only when it is pure water.
solve for mass water, mass water = density water Â·volume water. mass water = 1 g/mL Â· 250 mL. mass water = 250 grams. Now we have enough to find the mass of the salt water. mass total = mass salt + mass water. mass total = 25 g + 250 g. mass total = 275 g. Volume of the salt water is 250 mL. Step 2: Plug your values into the density formula.
