The mass of an object remains constant regardless of its location, so an object with a mass of 1 kg on Earth still has a mass of 1 kg on Neptune. However, due to Neptune's stronger gravitational pull (approximately 11.15 m/s² compared to Earth's 9.81 m/s²), the weight of that 1 kg object would be greater on Neptune. Weight is the force exerted by gravity on an object, so on Neptune, that 1 kg mass would weigh about 11.15 newtons.
According to NASA's figures, the mass of Neptune is 102,440,000,000,000,000,000,000,000 kg or 102.4 quadrillion kg, or if you want the scientific notation 1.0244 x 1026 kg. This makes Neptune around 17 times the mass of the Earth.
By the law of conservation of mass, it is still 28 kg.
Neptune Mass: ~1.0*1026 kg Volume: ~6.3*1013 km3
The mass of neptune is 1.0244 x 10 (to the 26th).
Neptune has a diameter of about 49,244 kilometers, making it the fourth largest planet in our solar system. It has a mass of about 17 times that of Earth, weighing in at approximately 1.024×10^26 kilograms.

The mass on Neptune is 50kg although this is only due to mass being gravity independant; assuming you mean it's weight.It's Weight on Neptune would be: 600kg.(weight = mass * g)

1 kilo is normally used to refer to 1 kilogram. This is a measure of mass and is NOT the same as weight. A mass of 1 kg is a mass of 1 kg - wherever it is.
Neptune has a mass of about 17 times that of Earth, which means it is much heavier than Earth.
Mercury: diameter 4880 km mass 3.302e+23 kg Venus: diameter 12104 km mass 4.856e+24 kg Earth: diameter 12756 km mass 5.9742e+24 kg Mars: diameter 6796 km mass 6.419e+23 kg Jupiter: diameter 142984 km mass 1.899e+27 kg Saturn: diameter 120536 km mass 5.685e+26 kg Uranus: diameter 51118 km mass 8.683e+25 kg Neptune: diameter 49528 km mass 1.0243e+26 kg
Uranus is the 3rd largest planet in diameter but in mass (8.683e25 Kg) it's less then Neptune
The sun is about 19,000 times the mass of Neptune.
Please don't confuse "mass" with "weight". Those are two quite different concepts. "Mass" is what is measured in kilograms, or in tons. From Wikipedia, Neptune's mass is 1.0243×1026 kg. This is equivalent to 1.0243×1023 tons, but for such large numbers, kilograms are commonly used.
